[SOLVED] Blynk + IR SAMSUNG TV Remote Power ON/OFF

[jasperdog]

yessssssssss it worked, thanks costas, i’m just starting to share the project to which i will accredit to you. Many thanks

[jasperdog]

@Costas Costas solved this issue and here is everything you need to create a blynk app to turn ON/OFF your SAMSUNG TV’

Download IRremoteESP8266master Library from Github:-
[IRremoteESP8266

Here is the finished working Code

  irsend.sendGC(Samsung_power_toggle, 71);
  }
  }
  void loop() {
  Blynk.run();

  }
  }

Here is the QR Code for the simple PUSH button, (must be set to PUSH and not SWITCH

Hardware side:- I used a NODEMCU IR led connected to D2

OBVIOUSLY the IR LED must be pointing at the TV to work.

Sory… i get this…
“error: ‘IRsend’ does not name a type”
I have all libraries installed…and just copy/paste the code from jasperdogJun

[jasperdog]

add the following 2 lines at the start, i will amend the code to reflect it above ok.

#include <IRsend.h>  // Needed if you want to send IR commands.
#include <IRrecv.h>  // Needed if you want to receive IR commands.

[jasperdog]

here is the revised code due to the IR library being amended some time ago.

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <IRremoteESP8266.h>
#include <IRsend.h>  // Needed if you want to send IR commands.
#include <IRrecv.h>  // Needed if you want to receive IR commands.



// You should get Auth Token in the Blynk App.

not working… sorry…

[jasperdog]

i don’t know, it works perfectly for me as per the code.

[juanjosecastillo]

OK, thanks anyway…i will keep trying!

[jasperdog]

i remember using a different approach to this, i’ll try and find my sketch and post it for you to try.

[jasperdog]

try this code, obviously change the gpio pin number for the esp8266 board you are using
in this line IRsend irsend(2); //an IR emitter led is connected to GPIO pin 2 (2)

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <IRremoteESP8266.h>
#include <IRsend.h>  // Needed if you want to send IR commands.
#include <IRrecv.h>  // Needed if you want to receive IR commands.


char auth[] = "your token";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "*************";
char pass[] = "*************";

IRsend irsend(2); //an IR emitter led is connected to GPIO pin 2 (2)
void setup()
{
  irsend.begin();
  Serial.begin(115200, SERIAL_8N1, SERIAL_TX_ONLY);
  Blynk.begin(auth, ssid, pass);
  
}
BLYNK_WRITE(V1){
  int onoff = param.asInt();
  if(onoff == 1){
    irsend.sendSAMSUNG(0XE0E040BF, 32); // 32 bits, no repeat

}

}
void loop() {
  Blynk.run();
    
}

[jasperdog]

i take it you are not using your own local server? if you are using your own local server then you need to add some more information to the code,

[juanjosecastillo]

It work!!
Im using global blynk server.
If i want to use my ir code, how i replace :
irsend.sendSAMSUNG(0XE0E040BF, 32); // 32 bits, no repeat

IR code is this:
unsigned int unknown[23] = {1250,450, 1250,400, 450,1200, 1300,400, 1250,400, 450,1250, 400,1250, 450,1200, 450,1250, 400,1250, 450,1250, 1250}; // UNKNOWN A32AB931 32 bit

[jasperdog]

that explains why you couldn’t use the original code which was for using a local server.

[jasperdog]

is it a samsung tv? because if it is then go back to using the original code without the server added code.

[juanjosecastillo]

Im trying to send IR codes to a Samsung TV, SONY muteki and a Peabody Heater(thats the “unknown” code) using blynk… only to control them with Google Assistant (thanks to IFTTT), i think i use multiple blynk virtual ports (V1 for TV power… and so…)

[jasperdog]

here is the original code less the local server bit.

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <IRremoteESP8266.h>
#include <IRsend.h>  // Needed if you want to send IR commands.
#include <IRrecv.h>  // Needed if you want to receive IR commands.



// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "********************************";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "**********";
char pass[] = "**********";

IRsend irsend(2); //an IR emitter led is connected to GPIO pin 2 (2)
void setup()
{
  irsend.begin();
  Serial.begin(115200, SERIAL_8N1, SERIAL_TX_ONLY);
  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
 /Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);
}
BLYNK_WRITE(V1){
  int onoff = param.asInt();
  if(onoff == 1){
    irsend.sendGC(Samsung_power_toggle, 71);
 }
}
    void loop() {
     Blynk.run();
  
}

[juanjosecastillo]

same error… something with “irsend.sendGC” comand…

[jasperdog]

the following turns my samsung tv on/off

unsigned int Samsung_power_toggle[71] = {38000,1,1,170,170,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,63,20,63,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,20,20,20,20,20,20,20,20,20,20,63,20,20,20,63,20,63,20,63,20,63,20,63,20,63,20,1798};

just remember to set the blynk button in th blynk app to a push and not switch
